Teaching:
In Spring 2008, I was the GSI for Math 239, Discrete Mathematics for the Life Sciences. The instructor was Lior Pachter.


Older Projects:
Under the direction of Lior Pachter and Bernd Sturmfels, two fellow students - Jason Morton and Oliver Wienand - and I undertook a project in the spring of 2006 analyzing microarray data. This took us to a meeting hosted by the Olivier Pourquié lab at the Stowers Institute in Kansas City. This inspired a paper entitled, Geometry of Rank Tests, and a follow-up paper Three Counterexamples on Semigraphoids, to appear in Combinatorics, Probability and Computing.
Jason presented our papers in September 2006 at the Probabilistic Graphical Models conference.
Our paper The Cyclohedron Test for Finding Periodic Genes in Time Course Expression Studies describes the implementation of a rank test inspired by algebraic combinatorics for finding interesting gene expressions in microarray experiments.

I attended a chicken genome workshop at Cold Spring Harbor lab in New York.
I have made a human reference-based annotation of the latest (May 2006) build of the chicken genome, under the guidance of Sourav Chatterji, using GeneMapper. "> UCSC Genome Browser.
